A TTOR/VEY JOHN MOSTEGNIK, OF CLEVELAND, OHIO.

WIRE-DRAWING MACHINE.

Application filed July 18, 1914.

To all whomit may concern:

Be it known that I, JOHN Mos'rEoNIK, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in VVire-Drawing Machines, of which the following is a specification.

My invention relates to improvements in wire drawing machines, and the improvements comprise the construction and arrang ment of parts substantially as herein shown, and described, and more particularly pointed out in the claims.

The object of the invention is to provide a machine for drawing wire to smaller diameters successively and continuously while maintaining the proper tension and feed of the wire during the successive changes in diameter thereof.

The object also embodies means to stop drawing operations automatically in the event of excessive pulling strains on the wire.

In the accompanying drawings, Figure 1 is a plan view of my improved machine, and Fig. 2 is a side elevation thereof. Fig. 2 is a diagram of the turns in the wire at the winding drum. -Fig. 3 is a sectional view on line 83, Fig. 1 longitudinally of the machine, and Fig. 4 is a cross section on line 44, Fig. 1. Figs. 5 and 6 are detail views of one of the drawing plates or dies. Fig. 7 is a plan view and section on line 7-7, Fig. 8, and Fig. 8 is an end view of the machine, some of the parts being broken away or omitted.

The machine is particularly designed to draw wire of small gage, but the invention is not necessarily limited to this special work. As shown, however, the machine comprises a main frame 2 which carries an open receptacle 3 for a suitable liquid in which the wire is immersed during operations. The wire w is fed from a reel 4 rotatably mounted on a bracket 5 at one side of the frame, and passes from the reel to the end idler wheel or sheave 6 of a. series of such wheels mounted loosely on the crossshaft 7 at one end of the frame 2. The wire is drawn from reel 4 by a sustained pull derived from the winding drum 8 on the vertical shaft 9 rotatably mounted upon frame 2 and driven by bevel gears 10 and 11 and power shaft 12. Drum 8 is stepped and slightly tapering and is provided with a Specification of Letters Patent.

pulley or sheave portion 14 at its lower end around which the wire to is given a turn as it comes from the last die or wire-drawing plate 15 in a row of such plates transversely of the machine. The end 16 of wire w is secured to the upper end of the drum, but before the wire is actually wound thereon, it is looped around a small spool 17 at one side of the drum, and passes between a set of staggered pins 18 on a pivoted arm 19 which is free to oscillate on the aXis of the spool, whereby all kinks and short spring bends in the wire are straightened and removed before the wire is wound in relatively large coils on the winding drum. The sheave portion 14 is arranged to pull the wire continuously on a straight line from the last die plate 15, and the wire is also guided by or passed around a sheave 20 on a transverse shaft 21 carrying the differential pulley or pulleys 22 for drawing the wire successively at different speeds through the series of die-plates 15 having die-openings of different diameters. The wire to is given one or more turns around each pulley 22 and passes to and around one of the sheaves 6 and thence to a die-plate 15, being guided and alined in its travel and making one turn around a Wheel 23, which is free to rotate and slide on a cross rod24 within receptacle 3. A plurality of wheels 23 serve for the successive stretches of wire to between the several sheaves 6, and the several die-plates, and a suitable liquid is contained within receptacle 3 in which the wheels are immersed to cause the wire to travel through this liquid before and after passing through the die-plates. A longitudinal channel 25 in the cross piece 26 which holds the die-plates carries away the drippings from the wire and die-plates, and a drip pipe 27 extends from said channel to a suitable receiving vessel 28. The die-plates 15 are loosely and removably seated in a longitudinal recess in the cross piece 26, and slots 29 in the walls of the cross-piece permit free lift and setting of the wire and the die-plates.

The die-plate with the largest wire-reducing opening is opposite reel 4 and the other die-plates have wire-reducing openings of smaller size successively to produce a gradual reduction of the wire in a continuous manner, and the pulleys 22 of different diameters accommodate the changes in length of the successive stretches of wire between every successive pair of die-plates and also ditions, being held thereat by a bow spring 34 which presses against the pivoted gear segment 35 in mesh with the gear teeth 36 on the bolt. A curved arm 37 on segment 35 extends through a side opening in the lower end of the drum, and actuation of said arm by hand or otherwise will withdrawand release the bolt from the shaft. To accomplish this result automatically I pivot a a lever 38 on the main frame opposite the circular path of the arm 3 7\and connect one end of this lever with the wire w at reel 4 by means of a link 39 having a small spool- 40 in running engagement with the wire. A slight resistance is applied to the free feed of the wire to produce an indirect line of travel of the wire, either by the weight of the link or by other means, and thus when the pull on the wire is increased to'straighten the wire in a more direct line from the reel to the end idler wheel (3 it happens that lever 38 is turned on its pivot an pro ected across the path of arm 37. When engage ment of the arm and lever occurs, the bolt 33 is released from shaft 9 and'the winding drum comes to immediate rest.

What I claim is:

1. A wire drawing machine comprising a main frame, an upright winding drum at one end of said frame, a reel at one side of the main frame of the machine and a side bracket supporting the same, a die plate centrally across said frame and dies therein sheaves to carry the wire at the rear of sai frame, a series of wheels corresponding to said sheaves about which the wire is adapted to run, and adilferential pulley for the wire opposite said dies.

2. A wire drawing'machine comprising a main frame, a liquid receptacle upon said frame, a series of wire-carrying wheels located in said receptacle, a set of sheaves behind said receptacle and a difierential pulley in advance of said receptacle and a series of loose die-plates for the wire arranged transversely of said frame between said wheels and said differential pulley, a winding drum for the wire and means to rotate the same, a separate reel for the wire and sheaves to receive the wire from said reel.

3. In a wire drawing machine, a frame having an open receptacle thereon and a slotted cross portion with a longitudinal channel therein adjacent to said receptacle,

a reel for the wire, a series of sheaves transversely arranged at the end of said frame, a series of wire-guiding die-plates loosely and removably mounted on said slotted cross portion of the frame, a differential pulley for the wire mounted opposite said dieplates, and a winding drum for the wire arranged upright upon said frame at one side of said pulley.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN MOSTECNIK.
